#1:
( Millimeter microwave
radar technology is no longer available, contact Stan Bleszynski for further
information +1(705)7612168 )
Ultra-high
precision (40um) ultrasonic close range (8cm)
proximity sensor available for OEM clients!
Non-contact
vernier-caliper replacement. Can also be used
for measuring
gas temperature (~0.02C) or gas composition.
Volume manufacturing available upon order!
Delivery time 8 weeks.
What does it do?
Non-contact
measurement of distance with 40um accuracy over full range.
Resolution 10um. Range: 8cm from face,
minimum distance 2.5cm.
Beam width 8mm, 1 degree
divergence. Fast 1s response (10ms,
100ms or 10s on special
order). Replaces mechanical vernier-caliper
gages. Replaces mechanical, inductive,
shafted LVDT, optical and
capacitive proximity distance sensors.
How does it work?
Measures
the time-of-flight using 1.4MHz ultrasonic bursts. It has automatic
calibration and temperature/humidity/gas
composition compensation.
How is it interfaced?
Powered
by 17-29V DC, 50mA.
Analog 0-5V voltage output for distance.
Analog combined temperature (speed of sound)
and envelope profile output, 0-5V.
Who may need it?
-
Machine shops: controlling dimensions and dimensional tollerance of
samples
during machining process.
-
Production departments: checking alignment and position of
objects in production lines. Thickness
measurement of sheets and bands.
Measuring bore-hole depth. Quality
testing.
- OEM
integrators: integrating it in the final product. Measuring of the
quantities of
items such as disks or sheets on a stack.
Paper sheet heights and thickness.
-
High accuracy fast air temperature measurement (0.02C) under a condition of
constant air
composition and humidity.
-
Monitoring of gas composition (providing that temperature is known).
What is the advantage of Ultraducer over other proximity sensors?
- Much higher accuracy than the existing ultrasonic sensors on the market.
-
non-contact (as opposed to LVDT sensors that require mechanical
contact with the target)
- more accurate than optical sensors
- longer range and much more linear response with a distance, than capacitive or inductive sensors.
-
less restriction on the type of the target surface. For
example Ultraducer will work against
a transparent target while optical sensors
require non-transparent and reflective targets.
Ultraducer will work with non-conductive
targets while inductive sensors wold not.
-
works through small holes down to the beam diameter; may be used for gageing
drill hole depths.
Product description.
Product Introduction (pdf, 0.05MB)
Test reports:
1) Linearity test (R&D lab)
2)
Customer's on-site test: measuring profile of a millimeter range microwave dish
antena.
Note: beam spread
angle of that particular transducer was enlarged to 3 degrees by
partially covering the
aperture with a tape, in order to facilitate obtaining good echo from
a curved surface.

Product #3: ROHADUCER
Ultra low cost, very high efficiency 40kHz through-air
ultrasonic transducer design suitable for automated mass-production (no potting
necessary). Ideal for
transducer arrays and consumer market, household applications.
